Docker Compose installed with the instructions from Step 1 of How To Install Docker Compose.Docker installed with the instructions from Step 1 and Step 2 of How To Install and Use Docker.A non-root user with sudo privileges configured by following the steps in the Initial Server Setup tutorial.To follow this tutorial, you will need the following: Nginx acts as a reverse proxy server that forwards requests to Gunicorn for processing.

Flask requires a web server to serve HTTP requests, so you will also use Gunicorn, which is a Python WSGI HTTP Server, to serve the application. You will define the entire stack configuration in a docker-compose.yml file, along with configuration files for Python, MongoDB, and Nginx. In this tutorial you will build, package, and run your to-do web application with Flask, Nginx, and MongoDB inside of Docker containers. Docker Compose uses a project name to isolate environments from each other, this allows you to run multiple environments on a single host. This ensures that there is version control throughout your container infrastructure. It allows you to define all your services in a single Compose file, and with a single command you create and start all the services from your configuration. Using Docker Compose provides ease of use over running multiple docker container run commands. Developers can use Docker to simplify the process of packaging and deploying their applications.ĭocker Compose has further simplified the development environment by allowing you to define your infrastructure, including your application services, network volumes, and bind mounts, in a single file. To continue the scalability of a developer’s tech stack, MongoDB is a NoSQL database is designed to scale and work with frequent changes. As a micro web framework built on Python, Flask provides an extensible way for developers to grow their applications through extensions that can be integrated into projects. Considering lighter weight options designed to reduce complexity and time-to-production for your application can result in a more flexible and scalable solution. Introductionĭeveloping web applications can become complex and time consuming when building and maintaining a number of different technologies.
